They are an important foundation for ensuring biosafety and environmental safety. Fume hoods and clean benches are not biosafety cabinets and should not be used in experiments or production processes involving microbial materials.

Features And Maintenance Of Class II Biological Safety Cabinets
Class II biological safety cabinets can prevent the spread of harmful aerosols and aerosols; provide protection for operators, samples and the environment. A better environment should be selected for the machine before commissioning. It is good to place it in a sterile room with air disinfection facilities. If the conditions are not available, the machine should be placed in a cleaner room with less movement of personnel. Adjust the height of each foot to ensure a stable and level operating surface. A special circuit should be used for the power supply of the workbench to avoid changes in the air flow rate caused by circuit overload.
